Application filed May 19,1905. Serial No. 261,273.

To (1.7] who/1t it Tit/1,7 concern:

Be it known that I, AUGUST SCHMIDT, gentleman, a subject of the King ofPrussia, German Emperor, residing at Langensalza, in the Kingdom ofPrussia, German Empire, have invented certain new and usefulImprovements in or Relating to Apparatus for Moistening and WarmingRooms or Apartments, of which the following is a specification.

My invention relates to improvements in apparatus for moistening andwarming rooms and apartments by means of warm moistened air, and aims toprovide in a manner as hereinafter more specifically referred to anair-moistening apparatus which shall be simple in its construction,strong, durable, efficient in its use, readily set up, and comparativelyinexpensive to manufacture.

With the foregoing and other objects in view the invention consists ofthe novel con- Struction, combination, and arrangement of partshereinafter more specifically described, and illustrated in theaccompanying drawings, wherein is shown the preferred embodiment of theinvention; but it is to be understood that changes, variations, andmodifications can be resorted to which come within the scope of theclaims hereunto appended.

In the drawings, Figures 1 and 2 are vertical sections at an angle ofninety degrees with respect to each other of an air-moistening device inaccordance with this invention. Fig. 3 is a sectional plan. Fig. 4 is avertical longitudinal section of a modified form. Fig. 5 is a horizontallongitudinal section thereof, and Fig. 6 is a vertical cross-section ofthe structure shown in Fig. 4.

In the construction shown in Figs. 1 to 3 the apparatus has acylindrical shape, and the divided air and water currents are directedat right angles with respect to and against each other, and in Figs. 4to 6 a box-shaped or rectangular arrangement is shown in which thesubdivided air-currents enter the moistening-chamber in straighthorizontal lines and meet divided waterjets sprayed in transversedirection, whereupon they are drawn by the fan and conveyed to the placeof utilization.

In the structure shown in Figs. 1, 2, and 3 air admitted at 1 firstpasses into an annular, inlet-chamber 2. The inner wall 3 of thischamber is perforated, so that the air can be drawn by the exhauster 4in divided jets from said chamber 2 into the moisteningchamber 5, inwhich the air meets water escaping in the form of jets or spray from acentrally-arranged pipe 6, provided with lateral openings. Whereupon themoistened air so formed rises and is conveyed in a wellknown manner tothe place of consumption through an adjustable pipe 7, arranged behindor above the fan 4. The pipe 6 is closed at the bottom and has connectedto the top thereof the forcing-pipe 8 of a pump 9, the suction-pipe 10of said pump communicating with the bottom of the air-moistening chamber5. 11 is a steam-pipe which can be open or shut off, as desired, andwhich is introduced into the top of the water-jet pipe 6 in a centralposition, its endprojecting down-- wardly in the pipe 6 and is providedwith a nozzle 12, so that the escaping steam acts as an injector, andthus besides its main objectthat is to say, the heating of the water andof the air to be moistened with itit also increases the spraying actionof the water. Water not absorbed by the rising air-current collects atthe bottom of the moistening chamber 5 and is sucked by the pump 9 andforced up through the pipe 8 in order again to pass into the jet-pipe 6,and so on. Water lost through the moistening of the air is replaced fromtime to time in any suitable manner.

In the construction shown in Figs. 4 to 6 the moistening-chamber 5 isbox-shaped or rectangular, and in its upper portion at the end oppositethe end at which is arranged the air-inlet chamber 2 and the air-inlet 1is positioned a fan 4, which is mounted at the inlet of the pipe 7,leading to the place or delivery of the moistened and heated air. Thewater-distributing device is arranged in this case in the Shape ofsuperposed perforated pipes 6, closed at their ends, and themoistening-water is supplied to them centrally through the delivery-pipe8 of a pump 9, having the suction-pipe 10 communicating with themoistening-chamber 5. pipes 6 are supported by brackets 13, secured tothe wall of the moistening-chamber 5. The moistening-chamber 5 ispreferably provided with a removable front wall 14 in order to give easyaccess to the interior. In the same way as in the constructionpreviously described steam-jet nozzles 12 are mounted in the water-jetpipes 6, the said nozzles being supplied with steam from a commonsteam-pipe 11. The steam-jet nozzles 12 are in this constructionarranged in pairs in each pipe 6 in order to enable the waterdistributed The water-jet in two directions and then escaping transversely or radially into the chamber 5 to be sufficiently heated andsprayed in a uniform manner. Owing to the injector-like action of thesteam, the moistening-water can, according to the quantity of steamadmitted, be heated to such extent that the warm air escaping from thefan 4 into the rooms will heat them to such an extent that even inwinter it Will not be necessary to heat the room or apartment in anyother Way.

Having now particularly described the nature of my invention, What Iclaim is 1. An air-moistening apparatus, comprising a receptacleprovided with a moisteningchamber and an air-inlet chamber, a perfo--rated partition between the said chambers and adapted to divide the airfed from the air-chamber to the moistening-chamber in the form of jets,a perforated water-distributing pipe arranged in the moistening-chamberand adapted to causethe supplying of water to said moistening-chamber 1nthe form of jets to intercept the jets of air thereby moistening thelatter, means communicating with the moistening-chamber and with saidpipe for withdrawing the surplus water from said chamber and returningthe same to said pipe,

and a nozzle extending in said pipe and adapted to supply steam theretounder pressure, and a suction-fan arranged in the upper end of saidreceptacle and in suitable relation with respect to aconducting-conduit.

2. An air-moistening apparatus, comprising a receptacle provided with amoisteningchamber, means for supplying air to said chamber in the formof jets, a perforated water-distributing pipe arranged in themoistening-chamber, adapted to cause the supply of water to saidmoistening-chamber in the form of jets to intercept the jets of air,thereby moistening the latter, means communicating with themoistening-chamber and with said pipe for withdrawing the surplus waterfrom said chamber and returning the same to said pipe, and a nozzleextending in said pipe and adapted to supply steam thereto underpressure.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

AUGUST SCHMIDT.
